The present invention relates to a low voltage DC-DC converter for a vehicle and, more particularly, to a low voltage DC-DC converter for a vehicle, capable of forming a circuit to drive a switching gate by using a differential pulse method which is robust against a noise environment. According to the present invention, robustness against a noise is improved by adopting a PWM signal transmission method of the differential pulse method by comparison with the PWM signal transmission method of a TTL level.
